Abstract

Organonitrogen compounds such as amine and amide derivatives are not only important nitrogen sources in synthesis but also important chemicals abounding in natural products as well as biochemically and pharmaceutically active molecules.(1) In addition to other methodologies such as transition-metal-catalyzed amination of organohalides, reductive amination of carbonyl compounds, etc.,(2) in recent years, N-alkylation of amines and amides with alcohols ...
